However, with the majority of them only returning to Leinster training last Monday, a few have been held back with an eye on next week and giving them an additional week to recover.
Although niggling injuries are persisting for Cian Healy, Jack McGrath, Marty Moore and Tadhg Furlong, the front row is still made up of Ireland internationals with Michael Bent, Richardt Strauss, who is set for cap number 90, and Mike Ross selected.
Devin Toner and Mike McCarthy make up the second row combination, Toner fresh from a first full Six Nations campaign with Ireland.
Jamie Heaslip is back to captain the side from number 8, with Kevin McLaughlin and Shane Jennings completing the Leinster pack.
There is plenty of experience in the backs as well with last weekend's centurion Ian Madigan again selected at number 10, with Eoin Reddan beside him and closing in on his own century - Saturday's sold-out game will be the 98th Leinster cap for the Limerick man.
The starting wingers are Luke Fitzgerald and Fergus McFadden with Gordon D'Arcy and Brian O'Driscoll back to continue their record-breaking centre partnership.
Rob Kearney returns to fill the full-back spot, with South African Zane Kirchner on the replacements bench.
Otherwise, Rhys Ruddock is still nursing a calf injury and Dave Kearney took a knock in training on Thursday and is another international who will not be risked for this game.
Both players will be assessed again early next week but three other Six Nations winners - Jordi Murphy, Sean Cronin and Isaac Boss - are included in the matchday 23.
The interprovincial derby at the Aviva Stadium is sold out with numbers presently at 51,157 - the final attendance will be confirmed on the night.
